Break out the type inference documentation from bindable property wizard

[matthewrdev]

The type inference engine that back the attached property, bindable property and value converter wizards needs to be broken out into its own documentation article.

Additionally, please review the behaviour of the ITypeInferenceService and update the documentation to reflect the new additions to its behaviour (such as being able to detect pluralisation and then generate lists of known types).
